Ok, I've had a broken Whirlwind for years now. Turned it on one day and the flippers no longer worked. My dad and I replaced the Q67 transistor, the K-1 relay, and have tested the U10 PIA. We've been scouring Marvin's Pin Repair site and are kind of stumped as what do to next. We did the switch edge test with the gator clips and the column tested out fine, so I don't think the switch matrix is a problem. So basically neither flipper works, and we're kind of stumped as what to do next. Anyone have any advice or have dealt with this before? The rest of the game functions fine just not the flippers.
